Frequently Asked Questions

What's the best indoor sauna for a spare bedroom?

A 2-3 person infrared sauna is ideal for spare bedroom installation. These units require only a standard electrical outlet, minimal ventilation, and fit comfortably in rooms 8x8 feet or larger while providing full therapeutic benefits for individuals or couples.

Do indoor saunas cause moisture problems?

Properly installed indoor saunas don't cause moisture problems. Infrared saunas produce minimal moisture, while traditional saunas require proper ventilation systems to manage humidity. Key factors include adequate ventilation, moisture-resistant flooring, and leaving the door open after use.

How much does it cost to install an indoor sauna?

Installation costs range from $2,000-8,000 for infrared saunas (mostly equipment cost), and $8,000-25,000+ for traditional saunas including professional installation, electrical work, and ventilation systems. DIY infrared installations can reduce labor costs significantly.

Can I put a sauna in my basement?

Basements are excellent locations for indoor saunas if ceiling height is adequate (7+ feet) and proper moisture management exists. Ensure good ventilation, waterproof flooring, and address any existing moisture issues before installation. Professional consultation recommended for basement installations.

What's the difference between indoor and outdoor saunas?

Indoor saunas offer year-round convenience, climate control, and privacy but require ventilation systems and moisture management. Outdoor saunas provide natural ventilation and space efficiency but depend on weather conditions. Indoor units are typically smaller and more energy-efficient.
